RE: Jett powered anyone?
hey guys,
I have a 60lx on a weston magnum and it totally rips the sky apart, but i cant seem to keep a glow plug more than one or two flights. The plug usually deforms and is useless i have tried os-8, fox plugs, mc-9, various os plugs i had in my box. they all have the same fate of black and melted or blown out elements. The mc-9 actually starts to fall apart! the pin in the center seems to be getting blown out. I am using 15% omega and a APC 9-9 cut to 8-9 and static on a new os-8 is about 18500 to 19000 rpm. I set it by leaning to max rpm and then backing off about 500 rpm. It seems if i go richer it doesnt get on pipe. Do you all have any ideas for plugs that will not fail each flight cause i am at a loss. i love the engine and it has amazing power but it is damn expensive to put a new plug in after each flight. oh, i have run about 3/4 of a gallon or so.
